>>>That's encouraging.   Although, you aren't driving your car hard at 
all--you're just cruising.   A motor that saw serious open track or ORR use would 
probably have a different story to tell.   But you raise an excellent point--how 
many of us really push our cars like that?

>>>It's not radiant heat.   There is a hole in two of the exhaust ports, and 
hot exhaust gasses are ducted up through the small port in the center of the 
heads and into the intake manifold.   So that is HOT air under extreme 
pressure.   Whether it's hot enough to eventually burn through 18-gauge (or whatever) 
steel is yet another matter for conjecture. :>)
